缺少异步操作文档？

问题描述

我找不到关于同步和异步操作的任何文档？



我希望在Visual Studio 2010中找到一个能够缩放和读取的键盘快捷键有关被调用参数的更多信息，但我找不到多少，可以，请你帮忙吗？

I cannot find any documentation on synchronous and asynchronous operations?

I was hoping to find a keyboard shortcut in Visual Studio 2010 that enables me to zoom, and read more information on the parameters being called, but I could not quite find much, can, you help please?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

namespace SyncDelegateReview
{
    public delegate int BinaryOp (int x, int y);
    class Program
    {

        static void Main(string[] args)
        {
            Console.WriteLine("Main() invoked on thread {0}.", Thread.CurrentThread.ManagedThreadId);
            //invoke Add in a synchronous manner
            BinaryOp b = new BinaryOp(Add);

            //invoke Add() on a secondary thread
            b = new BinaryOp(Add);
            IAsyncResult iftAR = b.BeginInvoke(10, 10, null, null); 
//WHAT DO THE LAST TWO PARAMETERS MEAN PLEASE?
            Console.WriteLine("Other work on thread in Main(..)");

            //obtain result of the Add()
            int answer = b.EndInvoke(iftAR);
            Console.WriteLine("10 + 10 is {0} ", answer);
            Console.ReadLine();
        }

        static int Add(int x, int y)
        {
            //write the ID of the executing thread
            Console.WriteLine("Add() invoked on thread {0}", Thread.CurrentThread.ManagedThreadId);
            //pause to simulate a lengthy operation
            Thread.Sleep(5000);
            return x + y;
        }
    }
}
